Abstract

fetched live from OpenAlex

The practical implementation of a precision analog cubing function in 0.18 /spl mu/m CMOS technology is presented. The cubing circuit consumes less power, has a smaller layout area, and achieves a higher operating frequency than previously published designs. The circuit advantageously utilizes the non-square-law current-voltage characteristics of deep-submicron CMOS to achieve a precise cubing function. The effects of component mismatch on the output error are explored. A common-centroid layout is used to reduce component mismatch due to linear process, temperature, and stress gradients. The cubing circuit has a total DC current draw of 6.3 mA from a single 1.8 V supply. The maximum error between the simulated and ideal cubing response is /spl plusmn/0.7 mV over the output range /spl plusmn/30 mV for operating frequencies up to 1 GHz.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
